Quizplus · Accepted Answer

Chaetae, also known as bristles, help earthworms anchor themselves in the soil and move through it. Without chaetae, the earthworm would have difficulty changing locations since it cannot anchor itself in the soil. The lack of chaetae would not prevent the earthworm from extending or shortening its body segments or from having a hydrostatic skeleton.
